When my new Minisforum MS-01 arrived, the first essential task on my to-do list was to perform a BIOS update. As any tech enthusiast would, I began by conducting a thorough search using Google and delving into Reddit posts to gather insights and prepare myself for the process.
Editor’s Note: This article was fully updated on August 7, 2025 to include new BIOS version 1.27
However, I quickly discovered that performing a Minisforum BIOS update is not as straightforward as one might expect. The process involves several nuanced steps, including navigating BIOS menus, managing secure boot configurations, and using UEFI and EFI shell environments. Understanding these technical aspects is crucial to avoid common pitfalls such as boot failures or update interruptions.
In this guide, I will walk you through every detail you need to know about the Minisforum BIOS update process. From preparing a bootable USB drive formatted with FAT32, disabling secure boot, to executing firmware flashing commands in the UEFI shell.
My Minisforum MS-01 arrived with the BIOS version 1.22
Some instructions suggested creating a bootable flash drive and extracting the downloaded Minisforum BIOS on the flash drive. Here is the location where you can download the latest BIOS. Further, it was mentioned to disable secure boot.
Troubleshooting Secure Boot Settings for Your Minisforum BIOS Update
As you can see in the BIOS menu (image below), Secure Boot was enabled in the BIOS, but the option to disable it was greyed out. I couldn’t figure out why I could not change this setting, which puzzled me.
Some online suggestions pointed to setting both an administrator BIOS password and a user BIOS password, but even after trying that, I still couldn’t modify the Secure Boot setting.
Then it hit me: why not install Windows 11? Since Windows 11 requires Secure Boot, this might unlock the ability to manage the setting. My Minisforum MS-01 had arrived without an operating system, as I planned to use it for Proxmox. However, before diving into Proxmox, I wanted to upgrade the Minisforum BIOS.
After installing Windows 11, I revisited the BIOS and to my relief, I could finally change the Secure Boot setting.
Creating a bootable USB drive for the BIOS
I followed the instructions from Brandon Lee on how to use Diskpart to prepare the USB disk drive.
diskpartnlist disknselect disk X # Replace X with the number of the disk you want to formatncleanncreate partition primarynformat fs=fat32 quickUnfortunately, using this method and extracting the downloaded BIOS file on the USB drive, I could not boot from the Minisform MS-01 using legacy bios or UEFI. I also needed shell.efi from here (credit to the post from Avamader in the STH community). I downloaded the ShellBinPkg.zip, extracted it and copied the shell.efi from this location D:BIOSShellBinPkgShellBinPkgUefiShellX64 to my USB drive.

Now, I was able to boot from the flash drive, getting the boot screen

The Crucial memory is perfect for the Minisforum MS-01, allowing both slots to be equipped with 48GB. The Minisforum has three M.2 HD slots, which I utilize for a Proxmox ZFS setup. Lexar or Samsung are excellent options.
